LOCOMOTIVE DRIVING-WHEEL.

7 To all whom it may concern:

Be it known that-I, ALBnR'r F. SHORE, a

citizen of the United States, residing at New York city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Locomotive Driving-Wheels, of, which the following is afull, clear, and exact specification.

Thls 1nve-nt10n relates to improvements 1nlocomotive driving wheels.

The driving wheels of a locomotive are connected to the reciprocatingoperating means and provided with a counterbalance. When such a wheelruns 01f One section of a rail and onto a succeeding section, a shock isdeveloped by the impact between the moving wheel and the rail at rest.

As now used, the rail receives by far the greatest percentage oftheshock, due to the ri 'dity otthe wheel, and, as' aconsequence, the lifeof the rail is shortened.

The object of this invention is to provide a wheel in the constructionof which-provision is. made for an elastic o'r yielding coun terweight,so that thevibrations caused by the impact of the wheel on the .rail arebroken up and absorbed with the advantage that the rails do not becomefatigued or brittie, and the-operating parts sufli'er less.

To this end, the invention comprises a wheel provided with a yieldingorcushion counterweight, and the shock of the wheel isfurther broken up bythe use of-slightly tangent spokes instead of the usual"radial spokes. a

The invention will be more fully understood from the accompanyingdrawings and the following description.

In the drawings Figure 1. is 'an elevation of a wheel embodying myinvention, the up-v ot the wheel being removed, and the use of a singlecover plate for per part showing ,my improved counterweightconstruction. Fig. 2 1s a similar view, showing another form of theinvention. Fig. 3 is a view partly insection',1showing the detailedconstruction of, the counterbalance. Fig. 4 is partly an edge view andpartly a view on line k4.- of Fig. 3. Fig.5 is a sectional Specificationof Ietterslatent,

by there is provided weight 10,

or springs, or

view on line 5-5 of Fig. 2, and vFig. 6 is a detail face view of one ofthe blocks used in the construction shown in Fig. 5.

In the drawings, the reference-nui'neral 1 is the hub of the wheel. n 2represents the spokes, noted, are not radial but slightly tangential, orset on an angle to the radius.

3 is the rim of the wheel, and 4.- the shoe.

5 represents the usual crank ,pin boss. 6 is a supporting flange onwallintegral with some of the spokes and the rim and wherelseparatecompartments or pockets 7 between the rim, spokes and the wall 6, andwhich are closed on the sides by a front and area-r cover-plate 8. I

Within the pockets 7 and adjacent the rim 3 isplaced cushioning oryielding blocks 9 of wood or other suitable material. The rest of thepocket is occupied by a granular comprising suitable solid fragmentscombined with a soft composition or hinder 1 1 to prevent the fragmentsfrom rolling about. Theresult of this construction is that the shock ofthetot-al weight of the wheel is prevented from being communicated tothe rail because of the. failure of the tangent spokes to transmit theimpact which requires a radial spoke. The tangent spokes. split up theimpact force into local and lateral vibrations within the wheel itself,while the granulated counterweight acts as a cushion in everydirection,-more particularly toward the rim where the wood is locatedand which is softer thanthe other walls of the pockets? and whichprevents the transmissio nof thes'hock to the rail.

The cover-plates and the wall G- by screws or bolts 12.

In Figs. 2, 5 and 6 I have shown solid blocks 13 inserted in the pockets7 and kept in position by bolts let. Wooden blocks 15, other yieldingelements, may be used both at the outer and inner ends of the blocks 13,though at .the inner endsthey may be, dispensed with. Tn thisconstruction-the cushioned, efif'ect will be parallel to the radius ofthe wheel but not necessarily at right angles thereto or onc'oncentric'lines.

8 are fastened to the rim If desired or found necessary, theyblocks 13may be entirely surrounded with wood or similar material giving the sameresult.

A combination of bot-h forms of the counterweight element may be used,and other details of construction may be varied within the scope of theinvention as defined by the claims.

I claim:

1. The combination of a wheel, a counterbalance carried by the saidwheel and having a yielding element as part of said counterbalance. j

2. The combination of a locomotive driving wheel, a counterbalancecarried by said wheel, said counterbalance containing a yieldingelement.

3. The combination of a locomotive driving wheel, a counterbalancecarried by saidwheel, said counterbalance containing a yielding-elementadjacent the rim of the wheel.

4. The combination of a locomotive driving wheel having a crank pinboss, a counterbalance carried by said wheel, said counterbalancecomprising a number of separate sections, and a yielding element in eachof the said sections.

The combination of a locomotive driving wheel having a crank pin boss, acounterbalance carried by said wheel, said counterbalance comprising anumber of separate sections, and a yielding element in each of the saidsections at the inner and outer ends thereof.

6. A wheel having a counterweight comprising a plurality of individualweight sec-- tions of granulated material.

7. A wheel having a counterweight comprising a pluralityof individualweight sections of granulated material and yielding material interposedbetween each of said sections and the rim of the wheel.

8. A wheel having a counterweight comprising a plurality of individualweight sections and front and rear cover plates for keeping saidsections in, the plane of the wheel. I

9. A locomotive driving wheel having its spokes set on an angle to'theradii of said wheel and separate counter-weights inserted between someof the said spokes and the rim of the ,wheel.

10. A locomotive driving wheel having its spokes set on an angle to theradii of said wheel and separate counterweights of gran 'ula tedmaterial inserted between some of depict of this patent may be obtaineiifor the said spokes andthe rim of the wheel.

11. A locomotive driving wheel having its spokes set at an angle to theradii of the -.wheel, separate counterweight members infive cents each,by. addressing the Commissioner of WeshingtomD. 0'.

serted'between the spokes and the rim of the wheel, and yieldingelements supported between the rim of the wheel and the said separatecounterweight members.

12. A wheel comprising a hub, a rim and tangentiallysupported spokesbetween said hub and rim, an inner supporting wall forming a pluralityof pockets between said spokes and rim and counterbalancing weightmembers supported in said pockets.

13. A'wheel comprising a hub, a rim and tangentially supported spokesbetween said hub and rim, an lnner supporting wall forming a pluralityof pockets between said spokes and rim and granulated counterbalancingweight members supported in said pockets.

14. A wheel comprising a hub, a rim and tangentially supported spokesbetween said hub and rim, an inner supporting wall fornr ing a pluralityof pockets between said spokes and rim, individual yielding memberssupported in said pockets adjacent said rim, and weight members in saidpockets between the said rim and the said yielding members.

15. A wheel comprising a hub, a rim and tangentially supported spokesbetween said hub and rim, an inner supporting wall formi11 a pluralityof pockets between said spokes and rim, individual yielding memberssupported in said pockets adjacent said rim, weight members in saidpockets between the said rim and the said yielding members, and meansfor retaining said weight and yielding members and the said pockets.

16. A wheel comprising a hub,'-a rim and spokes.counter-balancingelements carried by said wheel, and cushioning members interposedbetween said counterbalancing elements and the rim of the wheel.

17. A wheel comprising a hub, a rim and spokes. counterbalancingelements carried by said wheel, and wooden blocks interposed betweensaid counterbalancing elements and the rim of the wheel.

18. A counterbalance tor a locomotive driving wheel comprisinga'plurality of granulated counterweight members.

19. A counterbalance for a locomotive driving wheel comprising aplurality of sections of solid weight elements and yielding membersinterposed between the latter and the said wheel.

In testimony whereof, I atlix my signature, in presence of twowitnesses.
